Expansion Capabilities*Up to 192 drives with MD1200/MD1220 expansion enclosures on the MD3400 and MD3420 arraysUp to 180 drives with MD3060e expansion enclosures on the MD3460 array

Connectivity

Hot-swappable controllersMD34x0 and MD38x0x controllers are not compatible with the older generation arrays (MD32x0x and MD36x0x).

Single controller models: MD3400/MD3420: Directly connect up to two high-availability (HA)-configured servers or eight non-HA-configured servers to a single MD3400 or MD3420 storage system. Available with 4GB cache controllers.

Dual controller models: MD3400/MD3420/MD3460Directly connect up to four HA-configured servers or eight non-HA-configured servers to a single SAS storage system. Available with an option of 4GB or 8GB cache controllers.MD3060e contains two hot-swappable enclosure management modules (EMMs)

Controller featuresEach controller provides four 12Gbps SAS ports (MD3400/MD3420/MD3460); a total of eight for dual controller modelsEach controller contains 4GB or 8GB of battery-backed cacheDual controllers operate in an active-active environment mirroring each other’s cacheCache protection is provided via flash memory for permanent data protectionDynamic Disk Pools (DDP)* eliminates the need for complex RAID management while optimizing data protection, and can be used with existing RAID configurations Dual controllers are required for the MD3460 dense array

RAIDSupport for RAID levels 0, 1, 10, 5, 6Up to 180/192* physical disks per group in RAID 0, 10 Up to 30 physical disks per group in RAID 5, 6 Up to 512 virtual disksDDP*

MD3060e Dense Enclosure EBOD expansion enclosure designed for use with the MD3 dense array series only (MD3260i, MD3460, MD3860i, MD3860f)

Dimensions are identical to the dense array series (MD3260i, MD3460, MD3860i, MD3860f)

Controllers on the MD3 dense series arrays have either one 6Gbps SAS Out port (MD3260i) or one 12Gbps SAS Out port (MD3460, MD3860i, and MD3860f) for connecting to the MD3060e enclosure expansion for additional capacity (max 2 per dense array). For systems without premium feature activation, the physical disk limit is 120.

Four SAS ports and 2GB cache per controller ensure peak system performance for large database applications.

Optional turbo mode helps boost performance even further.

SSD support optimizes the system for the most demanding I/O applications.

New levels in flexibility and scalability

MD3200/MD3220 SAS arrays allow you to mix and match components to create a tiered-data environment.

Directly connect up to eight non-HA-configured servers or four HA-configured servers to a single MD3200 or MD3220 storage system.

Deploy up to a total of 96 additional HDDs by simply plugging in PowerVault MD1200 and/or PowerVault MD1220 expansion enclosures behind the MD3200/MD3220 arrays. This means you can scale your system with a mix of both 3.5” and 2.5” hard drives.

In dual-controller systems, hot plug additional storage enclosures without shutting down the system.
